Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a washing machine for washing dishes, vegetables or fruits. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Dishwashers on the market are generally divided into three types: tabletop, cabinet, and tank. Among them, tabletop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] At present, the structure of the relatively mature water tank type cleaning machine on the market is mainly as described in the Chinese patent "Water Tank Type Cleaning Machine" (application number: CN201310750968.1) with the authorization announcement number CN104224074B, that is, it includes a box body forming a washing space, the box body includes a water tank body and a cover plate rotatably connected to the water tank body, the bottom of the water tank body has a concave drain area at least in the central part, and the drain area is provided with a water pump that pumps the water in the drain area out to the washing space above the drain area, the drain area is covered with a drain plate with drain holes, and a rotating spray arm connected to the water pump fluid and having a water outlet hole is arranged above the drain plate. By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The sink body of the above-mentioned existing sink-type cleaning machine is made of stainless steel material, and the processing methods are mainly welding and drawing. Among them, for the welding process, due to the large welding deformation of stainless steel materials, it is difficult to control the dimensional accuracy of the sink, which limits the overall shape of the sink body, resulting in a single structure of the sink body, which in turn restricts the development of more functional structures of the sink-type cleaning machine. In addition, the welding process has extremely high requirements for the welding mold, low welding efficiency and high cost; for the drawing process, the deformation limit of the stainless steel material directly limits the drawing depth of the sink. The sink drawn by the drawing process generally has a depth less than the opening width of the sink. At present, it is difficult for the processes around the world to achieve a drawing depth greater than the opening width of the sink body, which causes the sink to occupy a larger installation space in the kitchen during installation and greatly limits the washing space of the sink.

[0005] The plastic sink body is highly plastic, and the depth of the sink body can be increased as needed, so that the kitchen space can be effectively utilized. However, since the water pump of the cleaning machine is located at the bottom of the sink body, the spray arm at the bottom of the sink body needs to be installed and used in conjunction with the water pump, resulting in that although the depth of the sink body is increased, the space in the top area of ​​the sink body cannot be effectively utilized. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a cleaning machine which can make the upper space of the water tank body be used independently and improve the space utilization rate of the water tank body in view of the current status of the prior art.

[0029] like Figures 1 to 8As shown, the cleaning machine of this embodiment is a water tank type cleaning machine, which is installed on a cabinet countertop for use. The cleaning machine of this embodiment includes a water tank body 1 having a washing chamber 10, and a drain plate 2 is detachably provided in the water tank body 1 so that the upper space 101 and the lower space 102 of the washing chamber 10 can be arranged relatively independently, and a first drain port 11 for draining water on the drain plate 2 is opened on the side wall of the water tank body 1. In order to facilitate assembly, a support 12 arranged along the circumferential direction is formed on the inner wall of the water tank body 1, and the drain plate 2 is mounted on the support 12.

[0030] In this embodiment, the side wall of the water tank body 1 extends outwards at a part near the corner to form a drainage channel 13. Correspondingly, the edge of the drain plate 2 extends outwards to form a mounting plate 21 that can be placed in the drainage channel 13. The first drain port 11 is opened on the lower wall of the drainage channel 13, and the mounting plate 21 is provided with a second drain port 211 corresponding to the first drain port 11. On the one hand, such a structure will not affect the use space above the drain plate 2. On the other hand, the waste water is guided to the edge of the water tank body 1 for discharge, which can prevent the waste water from polluting the fruits, vegetables or dishes on the drain plate 2. The second drain port 211 is installed with a drain valve 3 that can open or close the second drain port 211. When the drain valve 3 closes the second drain port 211, the area above the drain plate 2 can be used as an ordinary water tank, thereby improving the utilization rate of the water tank body. A filter screen 131 capable of filtering the outlet water is arranged in the drainage channel 13, and a drainage pipe capable of outputting the outlet water is connected to the outlet end of the drainage channel 13. The filter screen 131 can filter the drainage water to avoid pipe blockage.

[0031] The drainage channel 13 of this embodiment is arranged near the first edge of the drain plate 2, and the inner bottom wall of the drain plate 2 gradually slopes downward from the second edge arranged opposite to the first edge to the first edge. The inner edge of the inner bottom wall of the drainage channel 13 is flush with the support platform 12, and the inner bottom wall of the drainage channel 13 gradually slopes upward from the inside to the outside. The inner bottom wall of the drainage channel 13 is arranged at an angle of 170 to 178 degrees with the support platform 12.
